摘　　要：武装直升机实施低空突防时,在远程航迹规划得到的参考航迹上进行近程航迹规划来求得用于飞行的实际航迹,通过近程规划中面临的实际战场情况和机载探测、导航系统自身限制的分析,得到近程规划算法的主要限制和约束条件,并建立了快速蚁群算法和宽度优先快速搜索算法两种近程规划方法,在样例地形和威胁信息的基础上进行仿真,搜索最优航迹,计算航迹的各项指标,针对两种算法的特点进行了讨论,最后的计算结果可以作为近实时情况下的实际飞行航迹节点提供给导航系统。The trajectory for the real flight in the low penetration can derived from the real time shortrange trajectory planning based on the reference trajectory from the far-range planning.By the analysis of the actual battle situation and the airborne detection and navigation system,the main limitations and constraints can be figured out.The two planning methods,the fast ant colony algorithm and the breadthfirst fast search algorithm,were established.According to the terrain and threat information of the sample,the best path was found and its indexes were calculated by the simulation.After the discussion about the characteristics of two methods,the result can be taken as the near real-time flight path＇s node,which can be provided for the navigation system.
